Homeland Security Presidential Directive (HSPD)-5, “Management of Domestic Incidents”, called for the establishment of a single, comprehensive national incident management system. As a result, the U.S. Department of Homeland Security (DHS) released the National Incident Management System (NIMS) in March 2004. Revised in December 2008, the NIMS provides a systematic, proactive approach guiding departments and agencies at all levels of government, the private sector, and nongovernmental organizations to work seamlessly to prepare for, prevent, respond to, recover from, and mitigate the effects of incidents, regardless of cause, size, location, or complexity, in order to reduce the loss of life, property, and harm to the environment. HSPD-5 requires that all Federal Departments and agencies make adoption of NIMS by State, tribal, and local organizations a condition to receive Federal Preparedness assistance. To that end, the U. S. Department of Health and Human Services (HHS) requires that healthcare organizations implement NIMS in order to be eligible to apply for preparedness funding through the Assistant Secretary for Preparedness and Response (ASPR) Hospital Preparedness Program (HPP) grant program.
